Puzzle of Moon’s origin resolved
Simulations show that Earth probably collided with an unnervingly similar sister planet to form our lunar neighbour.
The ‘giant impact’ hypothesis, first proposed in the 1970s, suggests that the Moon was formed from the debris scattered when a Mars-sized planet slammed into the early Earth some 4.5 billion years ago. This fits well with what we know about the Moon, including its mass and lack of any significant iron core.

Mathematical proof for hot hand shooting in basketball
A study carried out at the University of Alicante brings the idea of the lucky streak back to the attention of the research community, offering sound mathematical proof in its favor.
Basketball fans, players and coaches all swear by the “hot hand,” the idea that players can experience winning streaks, being more likely to make a shot after having just made their last two or three shots. However, for decades, researchers repeatedly disproved the existence of the hot hand, claiming it was little more than a cognitive illusion. But this summer, in the latest twist to the story, economists Adam Sanjurjo and Joshua Miller of the universities of Alicante (UA) and Bocconi, respectively, published a working paper suggesting that this prior body of research is flawed by selection bias and that the hot hand might not be a fallacy after all.
